91442 - Technical-Geological Design

Learning outcomes

Students learn to solve main engineering geology problems which can be encountered in professional practice. The course emphasizes the importance of the geological and geotechnical model and parameter selection in calculations of ultimate and serviceability limit state calculations for both shallow and deep foundations, and discusses methods of soil improvement. Earth retaining structures considers systems ranging from gravity walls to composite construction (reinforced earth). Underground excavation, earth dams and artificial slope design are also treated with respect to possible geological problems.
